Handling multiple exceptions
- by the-banana-king
Hi there, I have written a class which loads configuration objects of my application and keeps track of them so that I can easily write out changes or reload the whole configuration at once with a single method call. However, each configuration object might potentially throw an exception when doing IO, yet I do not want those errors to cancel the overall process so that the other objects are still given a chance to reload/write. Therefore I collect all exceptions which are thrown while iterating over the objects and store them in a super-exception, which is thrown after the loop, since each exception must still be handled and someone has to be notified of what exactly went wrong. However, that approach looks a bit odd to me. Someone out there with a cleaner solution?
Here is some code of the mentioned class:
public synchronized void store() throws MultipleCauseException
{
MultipleCauseException me = new MultipleCauseException("unable to store some resources");
for(Resource resource : this.resources.values())
{
try
{
resource.store();
}
catch(StoreException e)
{
me.addCause(e);
}
}
if(me.hasCauses())
throw me;
}
